“Concentrate all your thoughts upon the work at hand. The sun’s rays do not burn until brought to a focus.” -Alexander Graham Bell

The Sun, contrary to what you might normally think about it, isn’t a constant, uniform source of radiation. It has an active surface, replete with temperature variations, sunspots, and occasionally a large flare or mass ejection.

But on very rare occasion, a flare like this makes it way through space and just happens to make its way towards Earth, where this hot, fast-moving ionized plasma collides with us. While the aurorae it produces can be spectacular, some of the other unwanted effects can be catastrophic!

I think you may be either missing the point of some of concerns, or setting up a straw man argument. The concern (at least as expressed by more responsible sources) isn’t that anyone is facing direct, personal danger for a CME but rather that the resulting infrastructure damage (GPS, power grid, air traffic control systems, mission critical electronics in utilities, hospitals, manufacturing, etc.) would be a massive blow to the world economy, and people would suffer from the secondary and tertiary impacts of this.

Is there any hope of actually getting informed in advance of collision? Unless someone is capable and responsible for alerting the general population — and actually willing to do so as warranted, we’re all gonna die.
